Beierplasm actually is a plasma pen, it is working by real plasma sine wave but not electronic energy. Through adjusting the frequency and voltage output to get different level plasma energy. Previous a lot "plasma" in the market, part of it is electronic machine and part of it is plasma machine.
We set in total 8 frequency level and 3 voltage output because country different.
Same energy output will cause different energy in different country since the altitude, temperature and moisture different.
It is one of the reason why we make 8 frequency in total.
Even in same province in China, we test 1800V and 50Hz in Shenzhen get enough power, however back to Guangzhou it is too weak
That's why we test energy perfect in somewhere and come to clients' hand they feel it is weaker. Through those multi control, any clent could find their right energy on these 24 level.
